Identifying a wetland

Updated 5 October 2020 3:56pm

To protect wetlands, we need to be able to identify them.

If you discover a wet, soggy or spongy patch on your land, it could be a wetland.

Wetlands are found wherever the water table is close to the soil surface, or in areas prone to flooding. They can be areas where ponding occurs and remains, and where springs emerge.

If you have a wetland on your property, you have an important role in the protection of this valuable resource.

Wetland identification guide

Wetlands range from those that are permanently wet, to some that are only wet for parts of the year. Check out our photo ID guide, which displays some of the key plants to look out for.
